    3. pNL26 Plasmid with insert: (seq 10318bp) (res map) (digests) (reverse complement)
      1. pNL26 insert PstI--HindIII:(pNL26 7371bp)
    4. pNL29 Plasmid with insert: (seq 8983bp) (res map) (digests) (reverse complement)
      1. pNL29 insert PstI--HindIII:(pNL29 6036bp)
  1. Recovery of genes: (2 days)
    1. Recover the plasmid from paper provided into solution.(method)
    2. Transform E.Coli strain DH5alpha. Screen with Amp 100ug/ml (as per ref.)(electroporation & heatshock)
    3. pick 3 colonies of each
    4. Overnight Culture x9(6 above and 3 form agar block provided)
    5. Miniprep
    6. Produce glycerol stocks

    3. Confirm translation (Namarski optics (direct interferance contrast microscopy method).
  1. Removal of four biobrick like restriction sites all in GvpL.
    1. [[http://www.kazusa.or.jp/codon/cgi-bin/showcodon.cgi?species=Escherichia+coli+K12+[gbbct]| DNA code Usage in Ecoli K12]]
